Discrete Simulation and Generation of the Power Law Noise

The generation of the power law noise is a sick field in atomic clock′s performance simulation.On the basis of analyzing the power law noise of atomic clock,two new methods in time and frequency domain to simulate the power law noise and generate it in this paper are proposed,five power law noises through the simulation are generated.The simulation results prove that real simulated value of no more than 2% in comparison with the academic value can be got.With N increasing,the simulated value more closed to the academic value.Besides it,the proposed methods is general,so it is of significance in simulating other color noise.
